2026 Toyota bZ (energy capacity 200 Ah): home charging cost in Massachusetts

At Massachusetts's residential electricity rate of 30.06¢/kWh, a 2026 Toyota bZ (energy capacity 200 Ah) (rated 25.8 kWh per 100 miles by the EPA) costs $7.77 to drive 100 miles on home charging, against $16.02 for the same distance in a car averaging 25.5 mpg on gasoline at $4.085/gallon. Charging at home is much cheaper than gas here: 51.5% less than gas per mile, here specifically.

What a year of driving costs

Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2026 Toyota bZ (energy capacity 200 Ah) charged at home in Massachusetts costs about $1,165/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $1,238 a year.

Cost of a full charge

A 2026 Toyota bZ (energy capacity 200 Ah) needs roughly 61 kWh to reach its EPA-rated 236-mile range, which runs about $18.33 at 30.06¢/kWh in Massachusetts.

How this compares nationally

This combination ranks 14,684 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Toyota bZ (energy capacity 200 Ah) alone ranks 10 of 400 models for efficiency; Massachusetts alone ranks 49 of 51 states for electricity price.

Next step: home charger installation

The numbers above assume Level 2 home charging is already in place — the electrical work behind that is a real, separate cost that varies by panel, wiring, and local labor rates, not something this page's per-mile math includes.
